- 6 Claims.

This invention relates to metal windows. One object of the invention is to provide an improved metal window frame construction which may be made of comparatively light metal and built into a masonry wall during the progress of th construction of the wall, the masonry being built directly into the metal frame so as to reinforce the same. This permits th use of lighter metal than would otherwise be the case. The inventlon also contemplates the provision of means associated with the frame for bonding the same into the masonry.

Another object of the invention relates to the provision of a frame construction of very simple configuration which can be made out of rolled sheet me al, preferably non-ferrous or non-corrosive metal, such as aluminum, bronz or stainless steel.

Anotherobject of the invention comprises the provision of a frame construction which may be erected in multiple units, so that any desired number of window units may be readily assembled in a single elongated window opening.

Another object of the invention is the provision of improved weather stripping means for doublehung windows in which a single weather stripping unit is utilized for both sashes.

Other objects and advantages of the invention will appear in connection with the following description of certain preferred embodiments of the invention chosen to illustrat the principles thereof.

In the accompanying drawings,

Figure 2 is a vertical section on lin 2-2 of Fig.

Figure 3 is a horizontal section on line 3-3 of Figure 1; r

Figure 4 is a vertical section on line 4-4 of Fig.

Figure 5 is a vertical section on line 5-5 of Fig. 3 showing the sash stile and a part of the window jamb and one of the spring anti-rattling members;

Figure 6 is a view similar to Fig. 5 showing a modification of the anti-rattling member;

Figure '7 is a perspective view of the anti-rattllng member shown in Fig. 6;

Figure 8 i a vertical section through a doublehung window showing a modification of the construction shown in Figs. 1, 2 and 3; and

Figure 9 is a horizontal section on line 9-4 of Fig. 8.

Referring to the drawings in detail, and particularly to Figs. 1 to 5, the window frame shown is composed of a header 20, a sill 2|, two side jambs 22 and a mullion 23. All of these parts are of such shape that they may be formed from rolled sheet metal, preferably of a non-ferrous or non-corrosive metal, such as aluminum, bronze or stainless steel.

Referring particularly to Fig. 3, it will be seen that the window jamb comprises a channel member having an outside wall 30 which preferably terminates at its outer edge or edge furthest from the window opening in an outwardly directed lip 31 which is set within the masonry, th space between the wall 3|] and the lip 3| forming a pocket for caulking 33. The wall 30 forms the outer stop bead for the window, and is bent upon itself at its inner edge to form an overhanging lip 35 and then is doubled back, as shown at 36, and then is bent transversely to form the web or back 38 of the channel. At the edge of the web 38 nearest to the inside of th building, the metal is bent to form a flange 40 which preferably terminates in a lip 4|. Centrally 0f the back or web 38 an off-set or rabbet 42 is preferably formed to provide a seat for a parting strip 44, which is removably secured in place in any suitable manner, as by screws 45. The web 01' back is also preferably formed to provide a rabbet 48 in which seat the inner stop bead 50 which has a flange 5l. terminating in a lip 52. The stop bead 50 is preferably removably retained in position in any suitable manner, as by means of screws 53. When the window frame is to be used, it is set in position and the wall built alongside of it, the masonry. especially th mortar or concrete, being filled into the channel formed by the side wall 30, the channel back or web 38 and flange 40. The channel is thus filled solidly with the masonry which reinforces the frame and enables it to hold its shape, although it may be made of relatively light metal. At th same time th masonry is bonded to the frame by means of bonding plates 55. These may be flanged as shown at 56 for attachment to the jamb channel by welding or in any other suitable manner, and are preferably provided with corrugations 5| or the like.

The mullion shown in Figure 3 is preferably formed out of a single piece of sheet metal bent to provide two webs Gu. each of which has an off-set 5| for receiving the parting strip 44, and each web being offset to provide a raboet 62 near its inner edge for engagement with a channel member 65 carrying inner stop beads 66 preferably terminating in lips 61. The channel memher 65 is removably held in position in any suitable manner as by means of screws 68. At the outer side of the mullion the webs 60 are bent upon themselves to form outer stop beads I5 preferably provided with lips I6. The mullion construction shown will thus be seen to be comprised entirely of two bent sheet metal channelshaped members interlocked and secured together. A very light, cheap and strong construction presenting a finished appearance from both inside and outside, is thus provided.

The upper and lower window sashes 80 and M are shown as formed of extruded hollow metal sections, a construction which we prefer, although any other suitable sash construction may be employed. The sashes are preferably arranged to slide in contact with opposite faces of the parting strips 44 and in order to hold them in contact with such faces and to assist in making a tight seal against the weather and to prevent rattling, the sashes are each provided with resilient devices adapted to slide along the inside of the stop bead and to hold the other face of the sash against the parting strip.

In Figures 4 to 7 we illustrate preferred examples of such yielding devices which as shown are in the nature of an improvement on the yielding device shown in U. S. Patent No. 1,808,608, dated June 2, 1931.

In Figures 4, 5, and 6 the yielding members are shown as arched spring wires 90 having bent ends 9| and 9Ia adapted to pass through holes 92 and 93 respectively in the side wall of a sash ,stile, the hole 93, being in the form of an elongated slot so as to permit yielding movement of the bent wire. The end 9Ia of the wire 90 may preferably be provided with threaded eyelet 98, and the hollow rail may have the small screw 99 inserted therethrough to engage the eyelet 98. It will be seen that the tension exerted by the yielding members may be adjustably varied by turning of the screw.

Figure '7 shows a modified form of yielding member in which the spring wire 95 is provided with a shoe 96 preferably formed of a U-shaped piece of metal into which the wire is inserted, the walls of the U being then clamped together as indicated at 91 so as to fix the shoe permanently to the wire. The shoe provides an enlarged bearing surface against the inside of the stop bead and permits the use of the kind of metal best adapted to slide smoothly, and without wear on the metal of which the stop beads are formed. It is thus possible to use a metal for the shoe which might be too soft or of unsuitable character to form the spring portion 95.

For further retaining the window weather tight and for guiding it against movement laterally in the plane of the window, while at the same time permitting a free raising and lowering movement at all times without sticking or binding, we provide weather. stripping or sealing means having resilient tongues I00 made of resilient, non-corrosive sheet metal and adapted to bear against the edges of the sash stiles. The outer edges ml of the weather stripping members are preferably of a single-thickness of metal without reinforcement, and may, therefore, be referred to as raw edges. This gives the weather stripping members great flexibility in a longitudinal direction and enables them to conform to the sashes at all times, so as to secure the best possible seal against the weather. The overhanging lips 35, 52, 61 and I6, respectively,

serve to guard and protect the edges of the tongues and also to limit the outward movement of the tongues when the sash is not in place, thereby permitting the resilient tongues to be so set as to be held under an initial tension. For cheapness of manufacture and ease of assembly, the tongues I00 are preferably part of a single sheet of metal, the central part of which between the tongues constitutes a shouldered piece I03 which is adapted to fit in the off-set or rabbet 42 formed in the web of the frame member, and held in such position by the parting strip 44 and its retaining screws 45.

The great simplicity of the construction shown is now apparent. Considering the jamb shown at the left hand side of Figure 3, it will be seen that this consists of the following four members plus a few attaching screws, namely, the flanged channel member, the inner stop bead, the parting strip and the double tongued weather strip. The mullion consists entirely of six members, namely, the member comprising the two webs 6t and the end wall 15, the channeled member 65 which includes the two stop beads, two parting strips and two double tongued weather strips.

Referring to Fig. 2, the header 20 of the window frame is shown as comprising a sheet metal channel member which is preferably of the same cross section as the jamb channel member 22. As only one of the sashes is required to make a sealing engagement with the header, a Weather strip is used which is provided with a single flexible tongue I00 mounted in any suitable manner, as by being formed on a base I 03a adapted to be held in a central rabbet in the header member by the parting strip 44. Instead of using a flanged inner stop bead member, a flat plate H0 may be mounted in the rabbet 62 and serves to cover the edge of the plaster III.

The window sill 2i is shown as formed of a single piece of sheet metal bent to provide a step I20 adapted to engage a resilient weather strip ill in the bottom rail of the sash, the sill also having an inner step I25 which is contacted by the inner face of the sash. At the inner edge of the sill the metal is preferably doubled to form. a lip I26 adapted to align with the inner stop beads and the inner edge of the plate H0. The hollow sill is preferably filled with concrete I28 to give it strength and rigidity and prevent it from being accidentally dented.

Referring to Figures 8 and 9, these show a modification of the window frame construction shown in Figures 2 and 3. The jamb shown in cross section in Figure 9' comprises a member I30 of extruded metal such as aluminum or bronze, which is provided with an outer flange I3I forming an outer stop bead and with a narrow flange I32 forming an extension of the flange I3I. At its inner edge the member I30 is rabbeted and holds an inner stop bead 5I preferably formed of an extruded section. The member I30 is shown as mounted upon a sheet metal backing member I40 which is provided at its outer edge with a flange I4I terminating in a. lip I42, the flange and lip forming a, weather stop and being preferably embedded between the masonry I43 and caulking material I44. The backing member I40 is shown as continued inwardly to the inside line I50 of the plaster wall of the room, the portion I5I of the backing member forming a metal reveal for the window opening. At its inner edge the member I40 is bent upon itself to form a corner bead I52 and is then extended in the form of a flange having an angular portion I53 and a fiat portion I54. These portions key into the plaster so that a strong and finished corner is provided between the metal reveal and the plaster wall. The corrugated tie plates 55 may be secured to the back of the jamb and the space back of the lamb and around the tie plates is preferably filled with masonry, as in the form of the invention shown in the previous figures.

The window header shown in Figure 8 is constructed similarly to the lamb member described, except that the flange Id, at the outer edge of the backing member, is preferably made wide to give added strength and to provide a recess for the counterbalance spring boxes I50. The header member 400 is similar in cross section to the jamb I30 and includes a recess 40I in which is mounted a stop bead comprising a base 402 and a top rail engaging member 403 which is in alignment with the outer face of the parting strip 44 and engages in snug relationship with the top rail of the upper sash when that sash is in closed position.

The sill shown in Figure 8 comprises a bent or extruded non-ferrous or non-corrosive metal member I10 having an inclined apron portion terminating at its outer edge in a downwardly turned flange III and provided with steps I12 and I73 for engagement with the bottom rail of the sash. An angle piece I15 may also be secured on the member I I0, the inner face of the vertical leg of the angle aligning with the edge of the parting strip- 44 and engaging with the outer face of the bottom rail of the lower sash when the window is closed so as to form a water breaker and assist in sealing the bottom of the window. The sill member I10 is shown as mounted upon a sheet metal subsill I80 which is bent at its forward edge to form a double flange I8I reinforcing the cornerof the outer sill member I'I0, the metal of the subsill being then bent downwardly to form a flange I82 adapted to cooperate with the flange III and the masonry to form a pocket for caulking I03. The subsill member is also formed with a shoulder I85 fitting under the shoulder I13 of the sill member. The subsill member is preferably continued inwardly to form a portion I86 corresponding with the reveals I5I, this portion terminating in a bead I52 and flange portions I53 and I54, as already described in connection with the jamb. A window recess within the room is thus provided which is entirehr lined with metal, the metal also providing corner beads for protecting the surrounding plaster.

The mullion construction shown in Figure 9 is formed of extruded metal parts and comprises two members I30 identical with the lamb members I30 already described. These members are held together by an outer channel or-filler I90, the back of which rests against the inner flanges I32, the legs of the channel having offset portions I92 which interlock against offset portions I93 formed in the members I30. At the inner side of the mullion the members I30 are held together by a channel member or filler 200 which has inner flanges I projecting inside of the inner edges of the members I30, the channel 200 also being preferably provided with lips 202 adapted to rest against the inner edges of the members I30. The parts of the mullion are secured together in any suitable manner, as by screws 205. As the members I forming the mullion are identical with the side lamb members I30, it will be seen that a window frame is provided which can be used either as a single unit with the members I30 on each side constituting jamb members, or any number of units may be assembled side by side with all of the members I30, except the two outermost members, constituting the side members of the mullions, adjacent members I30 being connected together by the filler channels I and 200. This permits great flexibility in the use of the window and various numbers of units may be assembled at the job to fill window openings of various size sashes as the architectural requirements of the building may determine.

While we have illustrated and described in detail certain preferred forms of our invention, it is to be understood that changes may be made therein and the invention embodied in other structures. We do not, therefore, desire to limit ourselves to the specific construction illustrated, but intend to cover our invention broadly in whatever form its principle may be utilized.
